A unique design of the stent that incorporates a drug-reservoir running along the stent struts. One or more drugs can be incorporated within the reservoir. Additionally other drugs can be coated on the surface of the strut enclosing the reservoir drug to facilitate sequential release of drugs. Thus, the design incorporating sequential release of muliple drugs facilitates to tackle the sequential complex biologic processes involved in renarrowing following stent implantation. The design also ensures that the drug present in the reservoir is released exclusively into the adjacent tissue without getting washed away into the blood flowing within the lumen. |
